Title: Innovations of Jesus Contreras-Espada
Introduction
Jesus Contreras-Espada is a notable inventor based in Linz, Austria. He has made significant contributions to the field of electrical engineering, particularly in the design and cooling systems of electric generators. With a total of 2 patents, his work showcases innovative solutions that enhance the efficiency and reliability of electrical machinery.
Latest Patents
One of his latest patents is a cooling system for the bushings of an electric generator. This system includes a casing that houses a stator and a rotor connected to a rotor shaft, which activates at least one fan to create high and low-pressure zones. The generator features multiple phases that are electrically connected to hollow phase rings, which in turn connect to bushings supported by the casing. These bushings have cooling circuits that allow a cooling medium to pass through, effectively cooling them. The outlets of the bushing cooling circuits are located in the high-pressure zone and are connected to the inlets of the hollow phase rings. Additionally, he has developed a method for cooling the bushings of an electric generator.
Another significant patent is a method for manufacturing a rotor. This method involves welding multiple elements together, where each element has a body with cavities and surfaces designed for welding to adjacent elements. The elements are vertically stacked to form a pile, with facing surfaces defining slots for welding. The cavities of adjacent elements create bores that extend within the pile. During the welding process, the bore is purged with an inert gas or mixture. The welding sequence is carefully planned, with the upper part of the bore being welded last.
